CN2900746Y - Cross beam structure of automobile door - Google Patents

Abstract

The utility model discloses a cross-beam structure of a car door. A bolster is symmetrically welded on two ends of the beam pipe, the welding face between the bolster and a covering in the car door is flat, which makes the welding firm and easy. The welding face between the bolster and the beam pipe is flat, which can increase the welding area and improve the welding strength. Meanwhile, a reinforcing rib on the bolster improves the bolster strength. According to the structure, the connection between the beam and the car door is safer and more reliable. The strength of car door structure is improved and the sound caused by opening or closing the car door is reduced.

Description

A kind of arrangements for automotive doors beam structure

Technical field

The utility model belongs to arrangements for automotive doors weldment structure.

Background technology

Existing arrangements for automotive doors crossbeam mostly is a simple transverse tube, direct and car door inside panel welds, because crossbeam is the pipe shape, with car door inside panel welding position is that point contacts, be not easy to be connected with the car door inside panel, the welding difficulty, and because solder side is too little, causes easily and send empty sound in the switch door car door.

Summary of the invention

The purpose of this utility model is to provide a kind of arrangements for automotive doors beam structure at the deficiency of prior art existence, improves the intensity of car door, reduces the abnormal sound that car door sends.

The technical solution of the utility model is as follows:

A kind of arrangements for automotive doors beam structure, it has a crossbeam pipe, be symmetrically welded a crossbar bracket at crossbeam pipe two ends, the solder side of crossbar bracket and car door inside panel is the plane, makes firm welding, easily, and with the welding position of crossbeam pipe be cambered surface, fully to contact with the surface of pipe, increase bonding area, increase weld strength.

In addition, two crossbar bracket also on the design ribs is arranged, be used to strengthen the intensity of carriage self, prevent flexural deformation.

Adopt said structure, can improve and be difficult for the situation that is connected between crossbeam and the car door inside panel, the raising weld strength, also safer when crossbeam is connected with car door, reliable, the structural strength at increase Qianmen, simultaneously, the different sound of the empty sound of the car door that produces in the time of also can improving opening/closing door of vehicle.

Description of drawings

Fig. 1 is the structural representation of this arrangements for automotive doors crossbeam;

Fig. 2 is the A-A cross-section structure of Fig. 1.

The specific embodiment

Referring to Fig. 1 and Fig. 2, this arrangements for automotive doors crossbeam is made of the crossbar bracket 2 that crossbeam pipe 1 and two ends are symmetrically welded, two crossbar bracket, 2 welding back keeping parallelism states.Crossbar bracket 2 be the plane with the solder side 3 of car door inside panel, with the welding position of crossbeam pipe 1 be cambered surface 4, increase weld strength, designed two ribs 5 on the crossbar bracket 2, the intensity of reinforcement carriage.

Claims (3)

1. arrangements for automotive doors beam structure, it has a crossbeam pipe (1), it is characterized in that: be symmetrically welded a crossbar bracket (2) at crossbeam pipe (1) two ends.

2. vehicle door beam structure according to claim 1 is characterized in that: crossbeam pipe (1) is welded in the cambered surface of crossbar bracket (2).

3. vehicle door beam structure according to claim 1 is characterized in that: two crossbar bracket (2) go up design ribs (3).
